Arthur T Knackerbracket has found the following story:

[...] Councils and local governments from Paris to Brooklyn have replaced high-energy sodium bulbs (the warmer, yellow ones) with energy-saving LED bulbs (with a blue light emitting diode, which can feel harsh in comparison). As well as street lights, most of us are exposed to blue light through smartphones, computers, TVs, and in the home.

Earlier this year, the World Journal of Biological Psychiatry published a paper by a group of prominent psychiatrists that warned of the potential effects of LED lighting on mental illness.

It raised concerns about the influence of blue light on sleep, other circadian-mediated symptoms, use of digital healthcare apps and devices, and the higher sensitivity of teenagers to blue light.

[...] Studies of the impact of blue light on healthy adults show it inhibits melatonin secretion which disrupts sleep and can affect quality of life, physical and mental health and susceptibility to illness. Previous studies of sleep disorders in children and adolescents show a clear and consistent relationship between sleep disorders and frequency of digital device usage.

    TFA mentions replacing current LEDs for health reasons. I think bright blue LED lights, at least in commercial products, are going to stick around, and won't be so easy to get rid of. Marketing departments have already discovered their value. Put two bland products side by side, one with a green LED and another with a bright blue LED. Idiots will go for the one with the bright blue LED. It is mind(less?) control, yea laugh if you want. Probably something with how it invokes some kind of relaxing evening/morning sky instinctive response. But consumertards will keep buying them and suppliers will continue to churn these things out.
